How Did Summer Weather Affect Your Roof?

Summer is hard on your roof. It’s hard on everyone’s! And here in Georgia, summers are particularly brutal. They’re one of the busiest seasons for roof repairs and maintenance work because they’re often when problems arise.If you’ve been putting off having your roof inspected by a professional roofer in GA, don’t wait. Here’s how this summer has already taken a toll on your roof.Humidity Leads to MildewIt’s no secret that summertime humidity ranges from “unbearable” to “hard-to-breathe” here in the Southeast. In your home, humidity isn’t just annoying, it can actually be destructive. One of your roof’s primary jobs is to regulate the humidity levels in your attic. That’s incredibly difficult for it to do if your roof’s ventilation wasn’t installed correctly, or if there’s too much or too little venting to begin with. It’s been a particularly humid summer in the Atlanta area which means older, improperly vented homes are at higher risk of mold and mildew collection in the attic than ever; organic growth in your attic can actually make your family sick. Call a local roofing professional today to determine whether or not the ventilation system in your attic is optimal.Heavy Rainfall Takes a Toll on Your Roof We’ve already had over 15 inches of rain here in metro Atlanta this summer, far more than the seasonal average. All that rain is great for lake levels, but it’s hard on your roof. Excess water can cause backups on your roof – particularly if your gutters are already clogged – which means water has nowhere to go but inside your house. A sagging or otherwise uneven roof also creates the perfect surface for water collection; standing water on your roof almost always leads to water intrusion. If you’ve noticed drips, drops, or other leaks pop up this summer, rest assured winter is going to make things much, much worse. Now’s the time to have your roof inspected, repaired, and even replaced if need-be.Storms Can Cause External DamageThunderstorms may be atmospheric, but they’re usually accompanied by high winds, driving rain, and occasionally even tree-felling lightning. (And don’t even get us started on hail!) Summer is the number one season in which roofs are damaged suddenly, from falling limbs to blown-off shingles to pock marks created by hailstones. Even if the damage seems minor from the ground it’s imperative you have a recently damaged roof inspected by a…

Why You (Probably) Shouldn’t Install a New Roof Over Your Old One

There are a lot of perfectly legitimate reasons to consider laying a new roof on top of an older roof. Convenience and cost are the two biggest, and it makes sense. Without having to tear off your old roof, wouldn’t installing a new roof be a much easier, cheaper process? That said, you’re right to be vary, vary wary if a local roofer suggests you simply install a new roof on top of your old one. In a vast majority of cases, the risks posed by “overlaying” a new roof far outweigh the potential cost and time savings. Here’s what you need to know about installing a new roof over an old one. Shingles Add Unnecessary Weight Did you know that most areas’ building codes actually limit the layers of shingles at two? There’s a reason for that: Most roofs aren’t designed to hold the exponential weight of multiple layers of shingles. A single square foot of shingles can weigh upwards of 250 pounds! The structural integrity of your roof could be in jeopardy if you apply too many layers of shingles, so overlaying is a particularly risky option for older homes. Your Old Roof Isn’t a Flat Surface Shingles, particularly asphalt shingles like those most common here in metro Atlanta, are designed to be installed on a flat surface. They don’t do a great job sealing over bumps and humps, which your old shingles certainly create. Of course, an overlaid roof will be installed on top of a relatively flat underlayer, but if there are any cupped, curled, or misshapen shingles underneath, those defects will simply transfer onto the new layer. Overlaying Doesn’t Reveal Anything One of the best things about having a brand new roof installed (after your old roof has been removed) is that a professional roofer can take a good, hard look at what’s going on underneath. If decking, flashing, or any other components of your roofing system need to be shored up, they’re easily addressed once the shingles are off. If your old roof isn’t removed, roofers have to guess what’s going on underneath and there’s little that can be done to tackle slow-emerging leaks, cracks, or other foundational issues. Replacing the roof’s tar paper – the paper layer installed on bottom to keep your roof watertight – is one of the primary purposes of replacing your roof altogether.…
